LOGGING-BUNK.

Specification of Letters Patent.

Application filed October 15, 1913.

Patented Feb. 1'7, 1914. Serial No. 795,359.

To all whom it may concern:

Be it known that we JONATHAN W. PUR- CELL and CHARLES W'. Pn'rriJoI-IN, citizens of the United States, residing at Mai-cola, in the county of Lane and State of Oregon, have invented certain new and useful Improvements in Logging-Brinks, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in logging bunks, and the object of the invention is to provide a device of this general character of a simple and comparatively inexpensive nature and having means of a novel and improved character whereby logs may be transported with convenience and facility with the possibility of danger reduced to a minimum.

The invention consists in the details of construction and in the combination and arrangement of the several parts whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in side elevation with a part in section of a logging bunk constructed in accordance with our invention, the logs adapted to be piled thereon being indicated by dotted lines as are also the positions of the arms disclosed; Fi 2 is a view in top plan of the body portion of our device as shown in Fig. 1; Fig. 3 is an end elevation of the device as shown in Fig. 1 with parts omitted; Fig. at is a transverse section taken substantially centrally of Fig. 1, with parts being broken away; Fig. 5 is a view similar to Fig. 4-, taken through an end of the body 1; Fig. 6 is a fragmentary view in elevation illustrating a detail of our invention, as'herein disclosed; Fig. 7 is an enlarged fragmentary sectional view illustrating a further detail of our invention; and Fig. 8 is a horizontal sectional view taken substantially centrally through Fig. 1.

As disclosed in the accompanying drawings, 1 denotes the body portion of our improved bunk which may be made of any preferred material and which may be of any desired size and configuration in accordance with the type of vehicle with which it is to be used, it being understood that the body member 1 is adapted to be suitably secured to a logging car, sleigh or any other vehicle that is especially adapted for the transportation of logs.

As hereinbefore stated, the body 1 may be made of any desired material but we have found in practice that good results may be obtained when such body 1 is made of wood and in which instance we bind the side faces of such member, as indicated at 2, by metal the upper marginal portions of such metal being adapted to project a predetermined distance, as at 3, above the upper surface or face of the body 1 in order to impinge the logs rested upon the body and thereby serve as a means to prevent endwise displacement of such logs. To further assist in maintaining the logs rested upon the body against endwise movement as would tend to displace the same, we have projecting upwardly from the upper face or surface of the body 1, the pointed lugs or spike members 4 adapted to coact with such lugs in a manner which is believed to be self-evident. We also find it of advantage to have these lugs or spike members 1 capable of detachable engagement with the body 1 so that if from any cause they should be come broken or otherwise unfit for use, they may be readily and conveniently replaced.

The opposite end portions of the body 1 are provided with the mortises in each of which is pivotally mounted an arm 6 adapted, when adjusted into a vertical position, to project a predetermined distance above the upper face of the body 1 and to serve as a means for maintaining the logs in piled relation.

In order to maintain the arms in their vertical adjustment, we provide each'of such arms 6 at a point in close proximity to the upper surface of the body 1 with an inwardly directed clevis 7 pivotally secured, as at 8, to the arm and to which clevis is secured an extremity of a flexible member 9, preferably a linked chain as herein shown, which member is adapted to be extended in the same general direction as the body 1 and projects through a suitable opening or aperture 10 in a laterally directed flange 12 formed on the metal binding 2 adjacent the end of the body 1 opposite to that to which the arm 6 is related. A hook member let is adapted to be hooked over the link 1 adjacent the outer face of the flange 12 and to contact therewith, whereby it will be readily perceived that the arm 6 is effectually held against outward movement under pressure of the logs which may be piled upon the body 1. It is also thought to be self-evident that when it is desired to unload the logs, it is only necessary to release the hook when the pressure of the logs will serve to throw the arm 6 outwardly. By this arrangement, it will be readily observed that the operator in releasing the logs is positioned to the side of the vehicle opposite to that from which the logs will be discharged and thereby being in a position absolutely free from danger.

In order that the flexible members 9 may not be fouled or interfered with by the logs rested upon the body or member 1, we provide in the upper surface of such body 1 the suitably directed grooves or channels 15 adapted to accommodate such flexible members and permit the same to have unobstructed movement therethrough.

Pivotally secured, as at 16, to the outer end portions of the arms 6 are the links 17 of a predetermined length having their free end portions formed to aiford an eye 18 through which a flexible member 19 is to be directed, such flexible member being herein shown as a linked chain. This member 19 is adapted to be passed over the top of the pile of logs and serves to maintain the pile against displacement, and such flexible connection or top chain 19 is locked in its proper position by the hooks 20 adapted to pass through the links of the connection 19 immediately adjacent the outer face of the eyes 18 of the links 17.

WVhile in no wise considered a part of our invention it may be well to state that in order to prevent loss of the various hooks 14 and 20, we have such members suitably anchored to the flanges 12 and arms 6, respectively, by the flexible members 21 of a predetermined length and also preferably in the form of a linked chain.

While we have referred to the arm 6 as being adapted to be maintained in a vertical position, we do not wish to be understood literally in this regard as it is possible in our improved bunk to adjust such arms outwardly as the differing sizes of the logs to be supported upon the body 1 may require.

From the foregoing description, it is thought to be obvious that a logging bunk constructed in accordance with our invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may maintain the logs in piled relation thereon and by reason of the fact that the possibility of danger is reduced to a minimum and it will also be obvious that our invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice.

We claim:

1. A logging bunk including a body, swingingly mounted arms carried by the body and capable of adjustment relatively thereto, means for locking such arms against movement in one direction, and flanges carried by the body and projecting above the upper surface thereof.

2. A logging bunk including a body, a swingingly mounted arm carried by the body and capable of adjustment relative thereto, and a flexible member connected directly to such arm and coacting with the opposite portion of the body for holding such arm against movement in one direction.

3. A logging bunk including a body, arm pivotally connected to the body below the upper surface thereof, and a flexible member connected to such arm below the upper surface of the body and coacting with the opposite portion of the body for holding such arm against movement in one direction, such flexible member being positioned below the upper surface of the body throughout the length of such body.

at. A logging bunk including a body provided with a channel in its upper face, an arm pivotally supported by such body in close proximity to an end of such channel, and a flexible member extending through the channel and connectedwith such arm and serving to limit the movement thereof in one direction.

5. A-logging bunk including a body provided with a mortise in one end thereof and having a channel in its upper surface in communication with such. mortise, an arm pivotally mounted within the morti e, and,

a flexible member secured to the arm below the upper surface of the body and directed through the channel and adapted to limit the movement of such arm in one direction.

6. A logging bunk including a body provided with a mortise in one end thereof and having a channel in its upper surface in communication with such mortise, an arm pivotally mounted within the mortise, and a flexible member secured to the arm below the upper surface of the body and directed through the channel and coacting with the opposite extremity of the body to limit the movement of the arm in one direction.

7. A logging bunk including a body provided with a mortise in one end thereof and having a channel in its upper surface in communication with such mortise, an arm pivotally mounted within the mortise, a flexible member secured to the arm below the upper surface of the body and directed through the channel, a perforate flange projecting laterally from the opposite extremity of the body and through which the flexible member is adapted to be passed, and means detachably engageable with the flexible member and coacting with the flange whereby such flexible member serves to limit the movement of the arm in one direction.

8. A logging bunk including a body provided with. a laterally directed flange and having a diagonal channel in its upper face, an arm pivotally supported by such body in close proximity to an end of such channel, and a flexible member extending through the channel and connected with such arm and coacting with the laterally directed flange to limit the movement of the arm in one direction.

9. A logging bunk including a body provided with a diagonally disposed channel in an exposed face thereof, an arm pivotally supported by such body in close proximity to an end of such channel, and a flexible member extending through such channel and connected with the arm at a point above its pivot and serving to limit the movement thereof in one direction.

In testimony whereof we hereunto aiflx our signatures in the presence of two witnesses.
